Yes, outrageously pricey and incredibly worthy! Don't wait to buy used, you won't find'em.
I've skied the TLT green plastic, Scarpa Maestrale, and then bought the TLT yellow carbon boot. And they are by far the stiffest. I am 6'2", 230 lbs, and ski aggressive. Wish Dynafit binders were more durable.
The TLT plastic is as stiff or stiffer than the Maestrale for downhill performance.
Walkability, Up-Hillability: no comparison to TLT for techy rock moves, articulation, and weight.
Fitting: I punched my carbon TLT yellows in the spring for 6th toe and punched for length and they held great over 7 weeks.
Skiing: Rather progressive flex blows through. But, these things are light as hale and ski amazing enough to never stop smiling. The smile factor margin is unbeatable.
Cons: 1. Let snow in with tongue removed for uphilling. 2. No cant adjustment on cuff. 3.Super thin shell is colder. 4.Thin plastic might wear through someday from talus walking and rock climbing; though i love ridgelines more than ever with this boot.
